Intravascular Ultrasound (IVUS): A Vital Diagnostic Tool for Heart Health
What is Intravascular Ultrasound (IVUS)?
Intravascular ultrasound (IVUS) is a diagnostic imaging procedure that uses high-frequency sound waves to create detailed, real-time images of blood vessels, especially those near the heart, such as coronary arteries. Unlike traditional angiography, which uses X-rays to produce 2D images, IVUS offers a 360-degree, cross-sectional view of blood vessels, allowing healthcare providers to assess the artery walls and identify conditions such as plaque build-up or narrowing.
The procedure can be used to diagnose heart conditions, plan interventions like stent placement, and monitor the effectiveness of previous treatments. It helps identify blockages, plaque, or other abnormalities in arteries, enabling early detection and better management of cardiovascular diseases.
How Does Intravascular Ultrasound Work?
IVUS uses a small catheter, which is inserted into a blood vessel, usually through an incision in the groin area. The catheter has an ultrasound probe that produces high-frequency sound waves. The waves bounce off the vessel walls and are transformed into real-time images by a computer, providing a detailed view of the vessel’s interior.
When is IVUS Used?
IVUS is often conducted during cardiac catheterization or as part of procedures such as angioplasty. It helps evaluate coronary artery disease, monitor plaque build-up, and guide stent placement. IVUS is also used to:
- Assess the severity of atherosclerosis and identify potential blockages in arteries.
- Evaluate the effectiveness of stent placement.
- Diagnose conditions such as heart attack, stroke, and pulmonary embolism.
- Guide procedures such as coronary artery bypass surgery (CABG) or percutaneous coronary interventions (PCI).
What to Expect During an IVUS Procedure
At TX Hospital, one of the top-ranked cardiac hospitals in Hyderabad, IVUS is typically conducted in our state-of-the-art catheterization lab (cath lab). The procedure involves:
- Preparation: The patient may be given local anaesthesia to numb the area where the catheter will be inserted. In certain situations, sedation or general anaesthesia might be administered.
- Catheter Insertion: A small incision is made in the groin, and a sheath is threaded into a blood vessel. The catheter with the ultrasound probe is then threaded through this sheath and guided to the coronary arteries.
- Image Capture: As the catheter moves through the vessel, the ultrasound probe sends out sound waves, capturing images of the artery walls.
- Procedure Completion: Once the images are captured, the catheter is removed, and pressure is applied to the insertion site to prevent bleeding. A bandage is applied to the site, and the patient will be observed for a few hours afterward.
What to Expect After the Procedure?
In most cases, if IVUS is performed on its own, you can go home the same day. However, if it was part of a more complex procedure such as angioplasty, you may need to stay in the hospital for observation for a few hours or overnight.
Benefits of IVUS:
- Comprehensive Imaging: IVUS offers a 360-degree view of the artery, enabling doctors to visualize the artery walls and surrounding tissue in greater detail than conventional angiography.
- Non-Radiation Based: Unlike traditional imaging techniques, IVUS does not involve radiation, making it a safer option for certain patients.
- Better Diagnosis and Treatment Planning: IVUS allows cardiologists to better assess plaque and determine the appropriate treatment strategy, whether that involves stent placement, angioplasty, or other interventions.
- Quick Recovery: Since IVUS is minimally invasive, recovery time is typically short, with most patients returning to their normal activities within a day.
How is IVUS Different from Angiography?
Both IVUS and angiography are used to assess blood vessels, but they differ in how they capture images:
- Angiography: Uses X-rays to create 2D images of the coronary arteries.
- IVUS: Uses sound waves to produce 360-degree cross-sectional images, providing a detailed view of the artery walls and surrounding structures.
